VALVE-SPRING COMPRESSOR.

Application filed March 15, 1927. Serial No.-175,452.1

ficulty is experienced by mechanics in com-' pressing such springs, as the same must be compressed, whenever the pin at'the end of the valve stem is removed to allow the removal or replacing of the valve.

The object of my invention 1S to provlde a tool which will fit all sizes of springs, whlch is quick and positive in its operation, and simple and economic in construction.

The tool consists of four long arms, and 7; two above and twobelow and all hinged together at one end andeach having a aw on the outer end, 10, 11, 12 and 13, shaped to squeeze in between the coils of the spring and to hold the spring both upon the end and sideways, and also atubular handle, 8,

which when pushed over the hinged end of the arms toward. the jaw ends brings the jaws together from all directions compressing and clamping the spring.

Figure 1 is a side view of the arms as used in connection with a spring. F gure 2 is a top View of the same. Figure 3 1s a detached sectional View of the tubular handle and Figure 4 is a side view showing a sprlng compressed with the tubular handle pushed on over the arms. g

The spiral spring, 5, and the washer, 14, always found at one end of such springs, are

at no part of the tool.

The arms 6 and 7 may be of any strong metal but preferably of smooth round steel. They are in pairs, the upper pair clamping the top and sides, and the lower pair clamp ing the bottom and sldes of the spring. 7 They may be hinged or fastened together at point 16, 17 in any manner, bolted or one coiled around. the other as 6 1s shown colled around 7 at point 16. The jaw ends of the arms with an upwardor a downward curve, 11,,

so as tobring the jaw arm along beside two or more of the coils of the spring, thereby, clamping the side of the spring to prevent it from bulgingout, and third, with a right orleft inward turn to bring the extremity of the upper arms over the top of an upper coil of the spring and the extremity of the lower arms under the bottom of a lower coil of the spring. The tip of the jaws, 12, 13, should be flattened, the more easily to be inserted between the coils of the spring.

At point 9 a hole is shown through the tubular handle through which a bolt or cotter pin may be inserted to prevent separation of the two parts of the tool when not in use and also to assist in pulling the jaws out lf)ro11n the spring when the handle is pulled What I claim as new and desire to secure by Letters Patent, is a i l. A valve spring compressor having four arms fastened together at one end, and each terminating at the other end in a curved jaw, the upper right jaw being curved out-- ward then upward before turning to the left.

inward to hook over the upper side ofa coil of a spring, and the inward turn or hook of the end of each arm being just long enough to keep the spring coils from slipping past it, the lower right jaw being curved outward then downward before turning to the left inward to hook over the lower side of a coil of a spring, the upper left jaw being curved outward then upward before turning to the right inward to hook over the top of a coil of a spring, the lower left jaw being curved outward then downward before turning to the right inward to hook over the lower side of a coil of the spring, each outward curve being concaved to approximate the circle of the coils of a valve spring, and means for pressing the four arms toward each other, substantially as shown.

2. A valve spring compressor having four arms fastened together at one end, and each terminating at the other end in a curved jaw, the upper, right jaw being curved outward then upward before turning to the left inward to hook over the upper side of a coil of a spring, the lower right jaw being curved outward then downward before turning to the left inward to hook over the lower side of a coil of a spring, the upper left jaw being curved outward then upward before turning to the right inward to hook over the top of a coil of a spring, the lower left jaw being curved outward then downward before turning to the right inward to hook 5 over the lower side of a coil of the spring,

each outward curve being concavecl to approximate tlle circle of the coils of a valve springancl a tubular handle of proper size to push on over the arms and press them toward each other, substantially as shown. 10
